Improving Figures using TikZ/PGF for LATEX: An Introduction

Vincent Darrigrand∗† Florian Faucher†

May 24th and 25th, 2016

Summary

This course provides an introduction to the various features of the LATEX package called TikZ/PGF, which is intended to the generation of scientific figures and drawings that are totally embedded within the document. The course is divided in two classes of two hours each. During the first class, we present the basic structure and keywords of a tikz picture to generate basic figures such as • Plots formed by clouds of data points with a customised legend, • Diagrams that can describe algorithms and • Sketches of a computational domain. The second session is devoted to present more advanced tools and library options such as • The external library to save compilation time, • The groupplot library that provides advanced features for plotting a group of pictures, • The tikz-3dplot package for 3D figures, • The pgfplotstable package to handle external data files, • Processes to automatize the plot structures for the display of results

Each participant is asked to bring a laptop with an up-to-date version of LATEX (TeX Live 2014 recommended). Optional, participants can also bring his/her own graphics and data.
